I am writing code to use TIFF as the standard image format for Color and
Monochrome images in place of Sun rasterfiles.  I am using parts of Sam
Leffler's TIFF library, and will contribute any fixes back to it.  The
problem I am having is that each sample image I have seen is completely
different, and very few conform to the 5.0 Spec from Aldus/Microsoft.  I
am especially curious what scheme NeXT used to compress the two bit
grayscale images from the Webster Disk.

What I'd like from this group is to get a wider sampling of image data
to test the robustness of the package.  I'll take any public domain
images that they can set up for anonymous ftp, along with a description
of the image, and what software package created it, and some simple
characteristics of the image. 

Sample Mail:

  From: imagejock@artist.berkeley.edu
  To: naughton@sun.com

  I have three images on artist.berkeley.edu:~ftp/pub/tiff

  rainbow.tif: 640x480 24 bit color tiff created from an AT&T Targa Board.
  document.tif: 1640x1280 4 bit CCITT fax dumped from FaxOmatic.
  mickey.tif: 512x512 1 bit Mac PackBits from PageMaker.

  good luck...  -ImageJock.


I'll summarize my findings to comp.graphics as well as the tiff@ucbvax
mailing list.

Thanks in advance.

-Patrick
